To all whom it may concern Be it known that we, VVILLIAM H. Mo- AnDLnand ROBERT B. MoARnLE, citizens of the United States, both residing atCamden, in the county of Camden and State of New Jersey, have jointlyinvented certain new and useful Improvements in llnvelop, Card, andSheet Feeders for Type-Writers, of which the following is aspecification.

Our invention has relation to certain im provements in a class ofautomatic envelop and card feeders for typewriters of the typeillustrated in United States Letters Patent, No. 9S5,4-29,-granted to usunder date of February 28th 1911, and in which is described a frame forcarrying a pack of enof March 14th 1911, in which as described therein,an approximately horizontal. paper carrying frame has its discharge endso constructed as to guide the paper downwardly to the typewriter,according to a v peculiar constructive arrangement of paper recelvingmechanism unfittcd to receive sheets or envelops in a horizontalposition, but with the same provided with bands or tapes stretchedaround the bend formed, and bearing on idler rolls carried by the bendof such frame.

The principal objects of our said invention are first: to providesimpler means to transmit motion to various mechanisms of the frame;second, to the provision of suitable mechanism to separate envelops,cards or sheets standing or lying in an inclined position, whilefeeding; third, to the provi* sion of the machine with means to protectthe envelops, cards or sheets after being acted upon by the typewriter;fourth, to the provisi n of means to mount flexibly feeding me hanism soas to allow the same to bear alt all points of contact uniformly againstthe envelops, cards or sheets while feeding; fifth, to the provision ofmeans so arranged as to adjust pressure of feeding mechanism againstenvelops, cards or sheets to be fed; and sixth, to the provision ofmeans so arranged as to maintain the envelops, cards or sheets at aproper angle While in bearing contact with feeding mechanism.

With these and other objects in view, as will be hereinafter more fullydescribed, our said invention generally stated, consists in' certainnovel features of constructive arrangement, as illustrated in theacconmanying drawings and as, particularly pointed out in the claims.

It is to be understood that various modifications in form, proportionsand minor de tails in the constructive arrangement as illustrated of thefeeding device, may be made without departing from the scope of our saidinvention or sacrificing any of the advantages of the same.

In the accompanying drawings z--Figure 1, a top or plan view of the saidfeeder, embodying main features thereof. Fig. 2, is a side elevation,looking from the left. Fig. 3, is a sectional elevation of the feedingand separating mechanism, longritlulinally along the line X--X of-l ig.1, Fig. 4, is a front elevation of the feeding roller, showingadjustment of the pressure of same against a pile or pack or envelops,cards or sheets to be fed; and Fig. 5, is a view of part of the bottomframe of the device, showing a spring for maintaining the euvelopsupporting plate carriage against feeding mechanism and alsoconvenienti'ueans for backing the carriage from said feeding mechanismso as to permit of the inserting of a fresh supply of envclops, cards orsheets.

In all the views of the drawings, similar numerals of reference are usedto indicate correspomling parts.

Referring now to the drawings, 1, is an envelop, card or sheetcarryingframe supported and connected to a typewriter, in a manner similar towhat shown in our United States Letters Patent No. 987,097, dated March14, 191].

a, is the platen of a typewriter.

a, is a sprocket secured to the spindle of the platen and connected tothe sprocket by means of a link belt. The sprocket is secured to theshaft 2, carrying a sprocket 2, and which in turn transmits motion to asprocket 8 by means of a link belt. The s rocket 8 is secured to androtates with t e shaft 8, carrying the sprocket 1(5. The sprocket 16,transmits motion b means of a link belt to a sprocket 17, on t e hub ofaspool-like feed roller or Wheel 11. The feed roller or wheel 11, iscarried by and rotates on a shaft '7. which is supported at its ends bymeans of ari'risf prfmembers l) and 10. The members 9 and lOQarepivotally mounted on the said shaft 8.

12 and 13, are rubber bands or the like forming frictional meansarranged around the enlarged ends of the feed roller or wheel 11. Thisfeed roller or wheel 11, as shown in Figs. 2, 3 and 4, rests on theidler rolls 50 and 51, which are mounted on the underside of the frame1, and extend up through openings in said frame. The mem bers 9 and 10,at one end are movably mounted on the shaft 8, and fulcrumed thereto isthe feed roller or wheel 11, and the opposite free ends are beveled orinclined respec- 'tively, at 9 and 10 as shown in Figs. 1, 2

and 4, and engaged by thumb-screws 19 and 20, extending through a bar18, which latter is held in place b ears 25 and 26, secured to the frame1; an these thumb-screws when operated are brought into engagement withthe free ends of said members 9 and 10, to permit of adjustment of thefeed roller or wheel 11, to or from the rollers 50 and 51, beneath. InFig. 4, the springs 19 and 20 bear respectively, on the thumb-screws 19and 20, with a pressure sufficient to automatically lock the same atwhatever point turned. The above referred adjustment for movablysupporting the feed roller or wheel 11, serves a two-fold purpose offirst keep in the said feed roller or wheel 11, from,

being lifted by the weight of the envelope, cards or sheets at C,pressing'down the incline; and second, of adjusting the distance of thesaid feed roller or wheel 11 from the stack of envelops, cards or sheetsC, at C The springs 19 and 20 as shown in Fig. 4-, bear respectively, onthe screws 19 and 20,

and by a pressure sufficiently to automati cally lock the screws atwhatever point turned.

14 and. 15, are two members carried by the shaft 8, 'to-maintain theenvelope or other,

articles at the- )roper angle, while being advanced to the eed roller orwheel 11.

28, is a supporting member for carrying the separating mechanism, asshown in Figs. 1 and 3, and which may be supported at one end by theshaft 8, and at the other by the shaft 27. The shaft 27 is supported atits ends by means of said cars 25 and 26, as fully shown in Fi 1. Thespring member 41, as illustrated in Fig. 3, may be secured to the shaft27, by a screw bolt 29, or other suitable means, to hold the springmember passing throu h the opening 41, under a pressure in contact withan adjustable thumb-.screw 30.

40, is a pin or projection on the member 41, passing through an openinin the supporting member 28, to keep t e connected members 41 and 42,from swinging out of alinement.

46, is a portion of the frame 1, bent at an angle. 45, is a memberscrewed or bolted to a piece it, and projecting into a small opening inthe frame 1.

44, is a frictional surface embracing the top of the member 45. Themember 43, is rotatably or otherwise mounted on the end of the member42, and adjusted to or from the surface 44,- by means of .the thumbscrew30, so as to accon1modate=the same to the thickness of an envelop, cardor sheet; the two members 43 and 44, engaging the envelops, cards orsheets at their middle portion only thus to allow of the free passage ofthe same at the corners thereof.

The pile or pack of envelops or other articles C, are pressed by aspring or by. gravity bear against the frictional periph eries of thefeed roller or wheel 11, and are kept at the proper angle for feeding bymeans of the members 14 and 15. The first envelop c, of the pack or pileis shown between the member 43 an surface 44. he end of the secondenvelop d, being pressed downward so as to come in contact with thefrictional surface 44, and held back until the envelop (2, has passedthrough the said opening. To the shaft 2, is secured two pulleys 3 and4, as illustrated in Fi s. 1 and 2, and over which pulleys pass t eendless bands, tapes or belts 5 and 6, and around and over rollers 58 topulleys 49" and 49, and back again to the pulleys 3 and 4." I

48 and 48 are brackets bent around and over the curved end of the frame1 at 1, as illustrated in Figs. 1 and 2, and supporting at the outerends the shaft 49, on which are rotatably mounted, the pulleys 49 and49*.

The forks 34 and 35, as illustratedin Figs.

.the pullevs 3 and 4, and which in conjunction with the forks 59 and 60,at the back of the said pulleys, are provided so as to pre vent theands, tapes or belts from workin ofl' of said pulleys. To the rear ofthe fee ing mechanism is an inclined envelopplato 21, adjustable todifferent angles, as shown in Fig. 2; and on the carria e 21, which ismounted upon wheels or rol ers to follow the envelope or other articlesC, down the inclined portion of the frame 1, so as to support and holdthe same at the roper angle, to be, engaged by the feed ro ler or wheel11.

36, as illustrated in Figs. 2 and 5, is a pin or projection carried bythe under portion of the front end of the carriage 91 and passing downthrough the slot 57, in the frame 1, so as to guide the carriage andhold the angle or envelop supporting plate at right angles to the travelof the carriage. The other end of the carriage is held in line with theslot 57, by a pin or projection 2-37, connected with the said carriage.The s, 'd pin or projection passes through said slot 57, as shown inFig. 5, and engages a spring 38, attached to the bottom of the frame 1.The said spring 38, tends to .push the carriage 21 toward the feedingmechanism. At the end of the member 37, it is arranged ring orhook-shaped and through which passes a lever 54, pivoted at 55, to thebottom of said frame 1 The lever 54, extends outward beyond the side ofsaid frame 1, to provide a linger-hold for backing the carriage 21, awayfrom the feeding mechanism so as to insert a fresh supply of envelope orother articles for being fed to the typewriter.

39, as illustrated in Figs. 2 and 5, is a member carried by the frame 1,and bearing and traveling back and forth on the rollers 56. The rollers56, are carried and support ed by the typewriter, in a manner as shownin our United States Letters Patent No. 987,097, dated March 14th 1911,aforesaid.

(30 and 60, are guides arranged so as to be adjusted to various sizedenvelops, cards or sheets and adapted to be released from said frame 1,by means of ordinary clamps ortho li e5.

illost typewriters more particularly the visible type, have guides infront of the platcnto hold the sheet or other article un i t'reed fromthe writing point, and which causes a sheet or other similar article tolean backward, and-in many cases to again enter the receiving roll r ofthe typewriter, if not restrained. '0 have provided a member 24:, asillustrated in Figs. 1 and 2, which provides for such conditions andwhich is pivoted to the sliaft's'ti), and rests on the platenimmediately in rear of the top thereof, and on which envelope, or othersimilar articles pile or collect after passing through the typewriterplaten-mechanism, each envelop or article being pushed upward by therotation of the platen, aided by the next succeeding envelop or othersimi ar article, still in the grip of the said platen-mechanism.

its the pile or pack of envelops or other similar articles have atendency to shuilie sidowisc from concussions of the typewriter, whileresting on the member 2%, hence the member 22, is so arranged andmounted in the block 23, as to prevent such action. The block :23, maycarried by the said bracket 1.8. Also the said member 22, made so as tobe adjustable to or from the end of the pile or pack of envelops orother 23. The said arrangement may be placed (in either or both sites ofthe envelops or other similar articles as may be preferred in practice.

Having thus described the nature and ob jects ofoiir invention, what weclaim as new and desire to secure by Letters Patent. is

1. The combination with a typewriter, of a support for carrying a pileof envelops or other similar articles to be fed to the typewriter, arotatable transverse shaft carried by said support, members movablymounted atone of their ends'on said shaft, a feed roller or wheelpivoially supported by said members, the latter at their opposite endsfree, adjusting devices adapted to engage the free ends of said memberson each side of said roller or wheel, means to actuate said feed rolleror wheel and means to prevent more than a single envelop or otherarticle to be fed at a time to the typewriter.
